CVSS 3.0
5.5 mediumCVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:NCVE-2018-1118
Medium (5.5). EPSS 0.4% chance of exploitation in the next 30 days.
Linux kernel vhost since version 4.8 does not properly initialize memory in messages passed between virtual guests and the host operating system in the vhost/vhost.c:vhost_new_msg() function. This can allow local privileged users to read some kernel memory contents when reading from the /dev/vhost-net device file.
